FAQs about why is my iphone 12 slow

Storage space full?

A common reason for slowdowns is a lack of storage space. When your iPhone’s storage is full, it can cause the operating system to slow down and apps to take longer to load. To fix this, you can try deleting unnecessary apps, photos, and videos. You can also try moving some of your files to iCloud or another cloud storage service.

Too many apps running in the background?

Another reason for slowdowns is having too many apps running in the background. When you open an app, it stays running in the background even when you’re not using it. This can drain your battery and slow down your phone. To fix this, you can try closing all of your unused apps by double-pressing the Home button and swiping up on each app.

Outdated software?

Out-of-date software can also cause slowdowns. Apple releases regular updates to iOS that include bug fixes and performance improvements. To make sure your iPhone is running the latest version of iOS, go to Settings > General > Software Update.

Hardware problems?

If you’ve tried all of the above and your iPhone is still slow, it’s possible that there’s a hardware problem. This could be anything from a bad battery to a faulty processor. To fix this, you’ll need to take your iPhone to an Apple Store or authorized repair center.


Although rare, malware can also cause slowdowns. Malware is malicious software that can infect your iPhone and cause a variety of problems, including slowdowns. To fix this, you can try scanning your iPhone with a malware scanner. You can also try restoring your iPhone to factory settings.
